Does Windows have a built-in duplicate file finder?

Hi everyone,

I'm looking for a way to clean up my PC and get rid of unnecessary files. I was wondering—does Windows have a built-in duplicate file finder that can help identify and remove duplicate files easily? I’ve seen a few third-party tools, but I’d prefer something that’s already integrated into the system if possible. If Windows doesn’t have this feature, what are some reliable alternatives that won’t bloat my system or compromise privacy? Any recommendations, tips, or settings I might’ve missed would be greatly appreciated. Thanks in advance!
